In
this recently published paper (here)
we describe the main characteristics of the semidiurnal lunar and solar
tides at middle and high latitudes of both hemispheres during a time period of
5 years (2009-2013). The tidal information is derived from wind measurements
provided by meteor radars at Davis (Antarctica), Rio Grande (southern
Argentina), Juliusruh (northern Germany) and Andenes (northern Norway). The
semidiurnal solar tides observed in the Southern Hemisphere (SH) show clear differences
when compared to the Northern Hemisphere (NH) and between middle and high
latitude locations at the same hemisphere. These differences are even larger
for the semidiurnal lunar tide, which shows stronger amplitudes from October to
March, and March to October, over Davis and Rio Grande, respectively. Our
results also indicate that the lunar tides at SH middle latitudes are
more prone to react to the NH stratospheric polar vortex influences, particularly
during the 2013 sudden stratospheric warming event.
